反向完整性测试 快速轻松识别泄漏的法兰连接
在工厂试运行期间或大修之后，需要对压力容器进行压力测试验证。传统的大容量充压泄漏测试方法可能需要大量使用花费高昂的设备、材料和专业工人。
当一个带压系统未通过压力测试时，必须对泄漏的法兰连接进行识别、拆除、重新加工和重新组装，直到成功完成压力测试。无法轻易识别的各个泄漏的法兰连接和计划外补救工作的需求，都花费高昂且耗时，通常会延迟装置的开车启动。
通过评估各个连接的完整性，RIGFLEX™ 垫片与传统的压力测试程序相比具有多种优势：快速、轻松地识别泄漏连接减少停机时间

反向完整性测试常见问题
Reverse integrity testing is a method by which you can prove the integrity or seal tightness of a flange connection without having to pressurise the whole system or a section of pipeline. This is obtained by pressurising the gasket directly when it’s inside the flange connection.
The RIGFLEX™ reverse integrity gasket works by utilising small annular cavities in the structure of the gasket, which are then pressurised by the use of an external pressurising port. Once pressurised and then isolated, the pressure is continually monitored for a short period of time to validate the integrity of that flange connection.
Flexitallic manufacture two different types of RIGFLEX™ gaskets.
The RIGFLEX™ FP is based on a tandem kammprofile design, typically using a stainless steel core with Corriculite® sealing face material.
RIGFLEX™ RJ is a metallic ring type joint reverse integrity gasket, which is used in API6A and B16.5 RTJ flanges in high pressure systems within the oil and gas industry.
Flexitallic typically manufacture these in stainless steel 316 or low carbon steel.
Flexitallic do not recommend that gaskets are reused.
Sizes are limited to standard ASME B16.5 flanges ½” through 24” NPS in classes 150 to 1500, and ½” through 12” #2500 flanges.
A number of these standard sizes are available from stock.
RIGFLEX™ gaskets may be available for other flange standards and bespoke/non-standard sizes, please enquire with the Flexitallic Applications Team.
The main advantage of using RIGFLEX™ gaskets is that you can prove the integrity of flange connections without having to undertake a very time consuming, and expensive exercise of pressurising an entire system.
Other benefits include that the gasket can be left in situ for normal service.
The use of Corriculite® sealing material is very important, it’s a new product manufactured by Flexitallic.
Corriculite® has been developed so that it is fire safe, corrosion mitigating and is suited for cryogenic applications from -200°C up to 250°C,
In addition to fire safety and corrosion mitigation and a wide temperature range, it provides an even tighter seal than traditional sealing products, such as graphite and PTFE.
Flexitallic can provide a full range of test pumps, hoses and connectors. Please speak to your local Flexitallic representative or distributor for further information.
